The legalization of physician assisted suicide (PAS) in Oregon and physician assisted death (PAD) in The Netherlands has revitalized the debate over whether and under what conditions individuals should be able to determine the time and manner of their deaths, and whether they should be able to enlist the help of physicians in doing so. Although the change in the law is both dramatic and recent,...

The maximum cable tension is a crucial parameter in the design of cable-driven parallel robot (CDPR) since various mechanical components CDPR must be designed to safely withstand loads induced by this tension. For CDPRs having number cables at least equal its degree freedoms (DOFs), article deals with determination smallest vectors allowing required wrench set feasible. problem formulated as mi...

—In this paper, the failure of wire­actuated parallel manipulators is examined considering their failure modes. A methodology for investigating the effect of actuator/wire failures on the force/moment capability of manipulators is presented, and the criteria for full and partial recovery from these failures are established. The methodology is also applicable for the cases that the minimum norm ...

Optimising the timing of delivery involves striking a balance between the benefits and risks of pregnancy prolongation compared with those of induction or elective Caesarean delivery. Birth of the baby is always in the best interest of the woman. For her, pregnancy prolongation has no direct benefit, but for the baby, the benefits may be large at gestational ages remote from term. This can be a...

On the 20th of May last, Dr Groves of Trinity requested me to see a woman who had been in labour for upwards of twenty-four hours, and who had fallen under his care after being abandoned by another practitioner on making several ineffectual, and it must be added, unskilful attempts to deliver. It was a case of twins, and the first child presenting naturally was delivered without trouble. The se...

BACKGROUND A vast number of biomechanical studies have employed inverse dynamics methods to calculate inter-segmental moments during movement. Although all inverse dynamics methods are rooted in classical mechanics and thus theoretically the same, there exist a number of distinct computational methods. Recent research has demonstrated a key influence of the dynamics computation of the inverse d...

The ability to modulate prey capture behaviors is of interest to organismal biologists as it suggests that predators can perceive features of the prey and select suitable behaviors from an available repertoire to successfully capture the item. Thus, behavior may be as important a trait as morphology in determining an organism's diet. Using high-speed video, we measured prey capture kinematics i...

This article proposes modeling, simulation and kinematic and workspace analysis of a spatial cable suspended robot as incompletely Restrained Positioning Mechanism (IRPM). These types of robots have six cables equal to the number of degrees of freedom. After modeling, the kinds of workspace are defined then an statically reachable combined workspace for different geometric structures of fixed a...
